<strong>Introduction</strong> <strong>to</strong><br />
<strong>IEC</strong> <strong>61850</strong><br />
Executive summary<br />
<strong>IEC</strong> <strong>61850</strong> is a collection of international standards defining:<br />
-how <strong>to</strong> describe <strong>the</strong> devices in an <strong>electrical</strong> substation and<br />
-how <strong>to</strong> exchange <strong>the</strong> information about <strong>the</strong>se devices<br />
- at configuration time and<br />
- at run-time.<br />
It simplifies considerably engineering and testing, savings several Mio € per year.<br />
It is <strong>the</strong> base for all developments in substation au<strong>to</strong>mation.<br />
Main products:<br />

<strong>IEC</strong> <strong>61850</strong> was developed by <strong>the</strong> <strong>IEC</strong> (International Electrotechnical Commission, Geneva)<br />
by a group of manufacturers (ABB, Als<strong>to</strong>m, Schneider, SEL, Siemens, Toshiba,..) and<br />
<strong>electrical</strong> utilities (Electricité de France, Iberdrola, Hydro-Quebec,…)<br />
<strong>IEC</strong> <strong>61850</strong> represents hundreds of person-years of work since 1997, one of <strong>the</strong> largest and<br />
most successful standardization group ever (comparable <strong>to</strong> IEEE 802.3).<br />

The switchboard in a home is a miniature substation:<br />
- distribution of electricity (<strong>to</strong> <strong>the</strong> different rooms),<br />
- control (switch on/off) and<br />
- protection (fuses).<br />

<strong>Introduction</strong> <strong>to</strong><br />
<strong>IEC</strong> <strong>61850</strong><br />
Object Model<br />
The <strong>IEC</strong> <strong>61850</strong> object model is <strong>the</strong> centerpiece of <strong>the</strong> standard.<br />
It relies on application know-how of <strong>the</strong> standards group.<br />
The model is used for:<br />
- system verification (“virtual maximum size substation”)<br />
- engineering of a particular substation<br />
- allocation of functions <strong>to</strong> devices in that substation<br />
- configuration of <strong>the</strong> real devices (IEDs and SCADA) and real network<br />
- testing and debugging<br />
The object model is implemented:<br />
-a) in <strong>the</strong> engineering <strong>to</strong>ols (<strong>to</strong>tal substation)<br />
-b) in <strong>the</strong> SCADA (relevant parts of substation)<br />
-c) in <strong>the</strong> devices (only local functions, need-<strong>to</strong>-know)<br />

<strong>Introduction</strong> <strong>to</strong><br />
<strong>IEC</strong> <strong>61850</strong><br />
The main features of <strong>IEC</strong> <strong>61850</strong><br />
- defines interconnection of IEDs based on E<strong>the</strong>rnet / TCP-IP / MMS<br />
- defines besides TCP/IP a Layer 2 traffic for time-critical data<br />
-defines an object model<br />
-defines application layer semantics for <strong>the</strong> objects<br />
-defines a substation configuration language<br />

<strong>Introduction</strong> <strong>to</strong><br />
<strong>IEC</strong> <strong>61850</strong><br />
Benefits of <strong>IEC</strong> <strong>61850</strong><br />
The benefit of an <strong>IEC</strong><strong>61850</strong> device is not in <strong>the</strong> price of <strong>the</strong> device: it<br />
is in lower cost <strong>to</strong> use <strong>the</strong> device.<br />
The benefit of an <strong>IEC</strong><strong>61850</strong> system is not in buying <strong>the</strong> system: it is<br />
in lower costs <strong>to</strong> engineer and commission <strong>the</strong> substation system.<br />
The cost of an installed device is 7 times <strong>the</strong> value of <strong>the</strong> device !<br />
“The flexibility provided by <strong>the</strong> <strong>IEC</strong><strong>61850</strong>/UCA-MMS<br />
pro<strong>to</strong>cols has <strong>the</strong> potential for saving millions of dollars<br />
in development costs for utilities and manufacturers,<br />
since it eliminates <strong>the</strong> need for pro<strong>to</strong>col converters and<br />
lengthy, complex database mapping when integrating<br />
devices from different manufacturers.<br />

Conclusion<br />
<strong>IEC</strong> <strong>61850</strong> is <strong>the</strong> base for all future developments in substation au<strong>to</strong>mation<br />
<strong>IEC</strong> <strong>61850</strong> is a successful standard in substations, because it put all competi<strong>to</strong>rs on an equal<br />
footing through <strong>the</strong> E<strong>the</strong>rnet / Internet technology.<br />
<strong>IEC</strong> <strong>61850</strong> defines an application object model that is independent from <strong>the</strong> <strong>communication</strong> and<br />
ensures long-term investment.<br />
<strong>IEC</strong> <strong>61850</strong> value resides in <strong>the</strong> savings in engineering and testing that it allows.<br />
<strong>IEC</strong> <strong>61850</strong> paved <strong>the</strong> way for o<strong>the</strong>r standards, such as wind mills, hydro and <strong>the</strong> same principles<br />
could be used in any standardized plant. .<br />
